Key Topics to Revise

1

Derivatives from First Principle

  • The derivative of a function is defined as the limit of the difference quotient.
  • Standard limits used: $\lim_{x \to 0} \frac{\sin x}{x} = 1$, $\lim_{x \to 0} \frac{\tan x}{x} = 1$.
  • Use trigonometric identities like $\sin C - \sin D$ and $\cos C - \cos D$ to simplify expressions.
2

Derivatives of Inverse Trigonometric Functions

  • Inverse trigonometric functions have specific domains and ranges
  • Their derivatives involve square roots and absolute values
  • Chain rule is essential when differentiating composite inverse functions
3

Product, Quotient and Chain Rules

  • Product rule: $(uv)' = u'v + uv'$
  • Quotient rule: $\left(\frac{u}{v}\right)' = \frac{u'v - uv'}{v^2}$
  • Chain rule: $\frac{dy}{dx} = \frac{dy}{du} \cdot \frac{du}{dx}$
4

Second Order Derivatives

  • Second derivative is the derivative of the first derivative
  • Denoted as $\frac{d^2y}{dx^2}$ or $y''$
  • Used to determine concavity and points of inflection
